Question

【題目】 Global warming is happening all around us. This experiment helps you learn how a greenhouse works, and how greenhouse gases influence the earth’s atmosphere (大氣).

What You Need:

Two thermometers

A notebook

A pencil or pen

A clear container

A watch or clock

A sunny area

What You Do:

1. Put the thermometers in direct sunlight. Let them sit in the sun for three minutes.

2. Draw two columns (欄), “Thermometer A” and “Thermometer B”, in the notebook.

3. After the three minutes, read and record the time and temperatures in the notebook.

4. Place one of the thermometers in the container and close it tightly.

5. Record the temperatures of the thermometers every ten minutes.

6. Discuss how the container influences the temperature.

What’s Going On?

The temperature outside the container is changing, as the warm air mixes with the passing cooler air. The air inside the container can’t mix with the air outside — it just gets warmer as the sunlight heats it up. A greenhouse works in a similar way: sunlight creates heat that can’t get out of the glass.

【1】What do you need in the experiment?

【2】How often do you record the temperatures of the thermometers?

A.Every five minutes.B.Every ten minutes.

C.Every fifteen minutes.D.Every twenty minutes.

【3】What can you learn from the experiment?

A.When the glass breaks.B.Why the sunlight is helpful.

C.How a greenhouse works.D.What the temperature changes.

Answer 1

【答案】

【1】D

【2】B

【3】C

【解析】

本文是一篇應(yīng)用文，是一個(gè)實(shí)驗(yàn)指導(dǎo)，指導(dǎo)大家如何做實(shí)驗(yàn)了解溫室氣體是如何作用并影響大氣的。

【1】細(xì)節(jié)理解題。根據(jù)What You Need: Two thermometers，可知需要兩支溫度計(jì)，故選D。

【2】細(xì)節(jié)理解題。根據(jù)5. Record the temperatures of the thermometers every ten minutes，可知每十分鐘要記錄一次溫度計(jì)的溫度，故選B。

【3】細(xì)節(jié)理解題。根據(jù)This experiment helps you learn how a greenhouse works，可知通過(guò)實(shí)驗(yàn)我們可以了解溫室氣體是如何作用的，故選C。
